I am not so sure you are.You can avoid wal mart completely, but wherever you go you will be buying the same stuff.
Amazon is your friend.I shop at Walmart some, today I need printer ink, they have it, I will check out the percussion caps today to see if they have any. If I didn't go to Walmart I might drive around all afternoon looking for the ink at other places.
One reason I go there is for the variety of stuff, their biggest problem for me is they sell out of something and it may be weeks before they restock, canning jars for instance.
My pet peeve for the local big box stores is they don't stock stuff for us oddballs.
Yesterday I needed an 8 32 die to chase the threads on a lock bolt I had buggered up a bit. I had somehow broken a high carbon bolt off in my previous die with no way to get the piece out, not enough to grab ahold of so I needed a new die.
I headed to Home Depot assured I would find a die there, it took the clerk 15 minutes to find two small Dewalt tap and die sets that you could fit in your back pocket, no individual dies.
Off to Lowe's, they had a display of individual taps with the correct drill bits but only the same minuscule tap and die sets as Home depot, no individual dies. The clerk working the tool section didn't know what a tap and die set was, where do they find these guys?
Frustrated I went home and searched the local hardware stores and auto parts places for the die. I could have made a 20 mile round trip to Are hardware to buy the die but pulled up eBay instead. For 50 cents more then the price at Ace hardware I could have the part delivered to my door in a couple of days.
I sure miss the tool section at Sears, unfortunately the one in town went belly up.
It's good to have a reminder of how lucky we are in the USA, in spite of the globies trying to subdue us. Thank God for the 2A.Your 'problems' amuse me. I have about three or four places in the whole of the UK where I can buy powder. The nearest is 180 miles. That's fifty quid in fuel or forty quid carriage. Caps the same and, without my Explosives licence - nothing. You are so lucky in the US. If had a big store that sold what I needed and cheaper than ayone else, my priciples would definately be sacrificed and I woud not criticise any-one else who did the same. Rant over, make a cup of tea.
